Measured data is automatically
saved to the memory whose in-
dicator is on the display when the
measurement is performed.
· When you press the C button to
change to another Meter Mode
memory, any power and speed
data already stored in that mem-
ory appears on the display.
· Whenever you display a Meter
Mode memory's contents, a
wave graph moves across the
display. The height of the wave
is according to the size of the
measurement data stored in the
memory.

USING THE METER MODE
The built-in sensor used to measure power and speed is preset to measure in the direction of a punch motion. This means that the values
produced in the Meter Mode cannot be used to compare the relative power and speed between two different motions (between punching
and kicking, for example).
Punch, Kick
Select a Meter Mode memory.
· Always warm up for about five
minutes before punching, kick-
ing, or any other strenuous ac-
tivity. Punching or kicking with-
out warming up can result in in-
jury. Take special care to warm
up and stretch your shoulders,
arms, and back. Do not overdo
punching and kicking, and
avoid performing too many
punches or kicks during the
same session.
· When punching and kicking,
take care to avoid hitting any
people, animals, or objects
nearby. Hitting another person
or object can result in personal
injury to you or another person.

· For punching, affix the watch securely
to either your left or right wrist. The
watch should be high enough on your
arm and tightened snug enough so it
does not ride down to the back of your
hand when you punch.
· For kicking, affix the watch securely
to either your left or right ankle. The
body of the watch should be located
so it is either at the front or side of
your leg. The watch should be high
enough on your leg and tightened
snug enough so it does not ride down
to the top of your foot when you kick.
· If you want to compare your power with a friend's,
you need to input some personal data. See "To
Input Personal Data".
· Fully extending your arm or leg
when punching or kicking can
produce pain in your joints,
bones, and muscles. To avoid
this, you should stop your
punch or kick just of full exten-
sion so your arm or leg joints
are still relaxed and slightly
bent.
· Should you experience any
pain when performing a mea-
surement, immediately stop the
activity you are performing and
consult a physician.
· Whenever performing a mea-
surement with the watch affixed
to your ankle, take particular
care that you do not lose your
balance and fall over, possibly
injuring yourself or others. Do
not try to raise your leg too high
when kicking.

tant!" before performing a punching or kicking motion.
